Slick video. It would appear sort of legit, but sort of questionable at the same time. People with cancer and people with HIV are desperate. Science is important and ultimately the best hope desperate people have. Internet videos like this are waving a big red flag.

If there's been a scientific breakthrough here, that's fantastic. But why has someone made this video? To raise money for research? To entice investors? Because it's not to announce a new treatment that is market ready.

...while the actual science behind this story is fascinating, the treatment is still at an extremely experimental stage and has only been tested in a handful of patients.And while we’re always keen to welcome exciting experimental cancer treatments, we also want to clear up a few misconceptions about what the research actually involved.To be absolutely clear, the doctors in the video did NOT inject HIV – nor a “deadly disease” – into a child.So who are these people, and what did they actually do?Turning the immune system on cancer
The research comes from Professor Carl H. June and his team in Philadelphia in the US. He’s a highly-respected scientist working on cancer, HIV and the immune system, and haspublished his work in hundreds of papers in many leading scientific journals over several decades.

To sum upBroadly speaking, we feel that this film is inspiring, and we’re always happy to see the fruits of promising new therapies for cancer. But to promote “injecting HIV” as a treatment is misleading.
One child surviving ‘incurable’ cancer is an amazing event, but there is a lot more work to be done to find out how best to use this new technology. At the moment it’s still highly experimental and expensive. It’s only being trialled in a very small number of patients, primarily to make sure it is safe, and so far we’ve seen that it doesn’t work for everyone.
In the case of the child whose cancer came back after treatment, the researchers found that her cancer cells had somehow stopped carrying the T cells’ target molecule. So it’s likely that other targets will need to be identified, to make the treatment more effective for more patients in the future.
On a positive note, there’s no reason why this type of treatment should be restricted to cancers affecting the immune system (namely leukaemia and lymphoma), although they’re much more accessible to the killer T cells. Researchers elsewhere are investigating how to target a range of different types of cancer with this approach.
There are several similar therapies being tested in the lab and in clinical trials around the world, including in the UK. And Cancer Research UK scientists are finding out whether harmless genetically-engineered viruses could be used as therapeutic vaccines, training the immune system to seek and destroy cancer cells.
It’s still early days for these exciting new approaches and there are many hurdles to jump, but we’re looking forward to the day when they can be used to treat patients on a wider scale.

Oncologists want to help their patients. Scientists want to develop cures for cancer. Out of the box research is an important part of science.

It's the video I wonder about. What was the motive for making it? You don't need a video to announce an important new cure. If the evidence is there, the medical and scientific community are not part of any conspiracy to hide such results, they will embrace the discovery.

To sum this up, there's a promising treatment, it's only been tested on a handful of patients. Test it further? Sure. Trust the motives of the people who made the video? I dunno, what are their motives?
